> Accumulo can specify visibility expressions for delete markers. During 
> compaction the cells covered by the tombstone are determined in part by 
> matching the visibility expression. This is useful for the use case of data 
> set coalescing, where entries from multiple data sets carrying different 
> labels are combined into one common large table. Later, a subset of entries 
> can be conveniently removed using visibility expressions.
> Currently doing the same in HBase would only be possible with a custom 
> coprocessor. Otherwise, a Delete will affect all cells covered by the 
> tombstone regardless of any visibility expression scoping. This is correct 
> behavior in that no data spill is possible, but certainly could be 
> surprising, and is only meant to be transitional. We decided not to support 
> visibility expressions on Deletes to control the complexity of the initial 
> implementation.
